So I've got this humbucker pickup from a guitar I got at a garage sale ages ago, and it wasn't working, so I thought I'd have a bit of a look inside. When I took off the back, I found that there were two wires, one coming from each coil, that were disconnected from the longer wire that comes out of it. I've got a picture attached, so you can see what I'm talking about. I'm guessing these should be soldered together, and these become the hot wire?

I'm also not entirely sure what the pickup is, but I know it's a Seymour Duncan, and I think it says 59N on a sticker on the back, does that mean it's a '59 neck pickup?

Any help is much appreciated

Actually, I can't upload the photo. If you need it to be sure I'll upload it elsewhere and link it here, but if you know what I'm talking about then it may not be necessary

Well with the way a humbucker works, the wire that comes from the inside of the coil is the ground, while the wire from the outside of the coil is the hot lead. If you can see the actual coils and the wires coming from them, then you can see which coil has the inner wire exposed, and that is the ground,

But I can't see that in your pic. So if I had to guess based on what I've seen in Duncan diagrams, I'd say that the wire coming from the coil with the adjustable pole pieces is the ground.
